[PATCH v5 12/14] mfd: da9063: Register RTC only on DA9063L

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The DA9063L does not contain RTC block, unlike the full DA9063.
Split the RTC block into separate mfd cell and register it only
on DA9063.

V2: No change
V3: Rework of mfd: da9063: Disallow RTC on DA9063L
V4: - Change the original failure text
    - Use PLATFORM_DEVID_NONE in mfd_add_devices
V5: Rebase on top of new 01 and 02 patches
